Description

Die Erfindung bezieht sich auf eine Schutzplanke nach dem Oberbegriff des Anspruchs 1.The invention relates to a safety barrier according to the preamble of claim 1.

Eine derartige Schutzplanke ist aus EP 1 722 037 B1 bekannt. Derartige Schutzplanken werden teilweise auch als Verkehrs-Leit-Einrichtungen bezeichnet. Hierbei handelt es sich um identische Gegenstände. Der Profilstahlpfosten weist dabei einen Flansch an seiner dem Schutzplankenholm zugewandten vorderen Seite auf, wobei an dem Flansch vorne der Befestigungsbügel angeordnet ist. Wenn der Pfosten beim Aufprall eines Fahrzeugs verbogen wird, besteht die Gefahr, dass der Befestigungsbügel aus dem vorderen Flansch gerissen und damit das Zugglied wirkungslos wird.Such a protective barrier is off EP 1 722 037 B1 known. Such guard rails are sometimes referred to as traffic guidance devices. These are identical items. The profile steel post in this case has a flange on its front side facing the guard rail spar, wherein the mounting bracket is arranged on the front flange. If the post is bent on impact of a vehicle, there is a risk that the mounting bracket torn from the front flange and thus the tension member is ineffective.

Ferner ist aus EP 1 816 263 B1 , die den nächsten Stand der Technik bildet, eine einfache Distanzschutzplanke bekannt, bei der an dem von dem Schutzplankenholm abgewandten hinteren Ende des Abstandshalters eine Lasche zur Befestigung eines Abspanngurtes vorgesehen ist, wobei der Abspanngurt durch miteinander verbundene Gewindestäbe ersetzt ist. Damit wird jedoch keine wesentliche Verbesserung der Rückhaltefähigkeit der Schutzplanke erreicht.Furthermore, it is off EP 1 816 263 B1 , Forming the closest prior art, a simple distance protection plank is known, in which at the remote from the guard rail rear end of the spacer, a tab for attachment of a guy belt is provided, wherein the tension belt is replaced by interconnected threaded rods. However, this does not achieve a significant improvement in the retention capacity of the guardrail.

Aus der EP 2 050 876 A1 ist ein Fahrzeug-Rückhaltesystem bekannt, dessen Schutzplanke über Distanzhalter von Pfosten getragen wird. Ein Spanngurt ist rückseitig an den Distanzhaltern befestigt. Die Distanzhalter sind über U-förmige Verbindungsklauen an den Pfosten festgelegt. Die Verbindungsklauen sind seitlich mit Schraubbolzen und -muttern an den Distanzhaltern befestigt.From the EP 2 050 876 A1 For example, a vehicle restraint system is known whose guardrail is supported by posts via spacers. A tension belt is attached to the back of the spacers. The spacers are fixed to the posts via U-shaped connecting claws. The connecting claws are fastened laterally with bolts and nuts to the spacers.

Die EP 1 921 211 A1 offenbart eine Verkehrs-Leit-Einrichtung, die eine an Stützen befestigte Leitplanke umfasst. Zur Stabilisierung der Stützen sind über der Leitplanke zwei Zug-Anker an den Stützen angebracht. Bei den Zug-Ankern handelt es sich um Gewindestäbe.The EP 1 921 211 A1 discloses a traffic guidance device comprising a pillar-mounted guardrail. To stabilize the supports, two pull anchors are attached to the supports above the guardrail. The train anchors are threaded rods.

Aufgabe der Erfindung ist es, eine Schutzplanke hoher Schutzwirkung bereitzustellen, welche insbesondere durch Nachrüsten bereits bestehender Schutzplanken geschaffen werden kann.The object of the invention is to provide a protective barrier high protection effect, which can be created in particular by retrofitting already existing crash barriers.

Dies wird erfindungsgemäß durch die im Anspruch 1 gekennzeichnete Schutzplanke erreicht. In den Unteransprüchen sind vorteilhafte Ausgestaltungen der Erfindung wiedergegeben.This is inventively achieved by the characterized in claim 1 guardrail. In the subclaims advantageous embodiments of the invention are shown.

Nach der Erfindung weist der Profilstahlpfosten einen von dem Schutzplankenholm abgewandten, äußeren oder hinteren Flansch auf. Der Befestigungsbügel weist einen mittleren Abschnitt zur Aufnahme des Gewindestabs und beiderseits des mittleren Abschnitts je einen mit dem äußeren Flansch des Pfostens verschraubbaren Endabschnitt auf.According to the invention, the profile steel post has a remote from the guard rail spar, outer or rear flange. The mounting bracket has a central portion for receiving the threaded rod and on both sides of the central portion depending on a screwed to the outer flange of the post end portion.

Damit wird eine erhebliche Verbesserung der Schutzwirkung erreicht, da sich die Pfosten mit ihrer Rückseite an den Gewindestäben bei einem Aufprall abstützen. Die Deformation der Pfosten bei einem Aufprall ist damit wesentlich herabgesetzt, obgleich die Schutzplankenholme stärker eingedrückt werden können. Da die Pfosten weniger deformiert und damit weniger in Aufprallrichtung verbogen werden, hält di erfindungsgemäße Schutzplanke insgesamt einem Aufprall viel besser Stand.Thus, a significant improvement in the protective effect is achieved, since the posts are supported with their back on the threaded rods in an impact. The deformation of the posts in a collision is thus significantly reduced, although the guard rail spars can be pressed more. Since the posts are less deformed and thus less deflected in the direction of impact, the guard rail according to the invention as a whole withstands an impact much better.

Zudem weist die erfindungsgemäße Schutzplanke standardmäßige Abstandshalter auf, die zur Befestigung an dem Pfosten mit einem Schenkel versehen sind, der mit dem äußeren Flansch des Pfostens verschraubbar ist.In addition, the guard rail according to the invention on standard spacers, which are provided for attachment to the post with a leg which is screwed to the outer flange of the post.

Die Abstandshalter sind durch ihre Befestigung an dem Schutzplankenholm und ihre Ausbildung so ausgelegt, dass bei einem Aufprall der Schutzplankenholm nach oben geschwenkt wird, sodass auch größere Fahrzeuge entlang dem Holm gleiten können, bis sie zum Stehen können.The spacers are designed by their attachment to the guard rail spar and their training so that in an impact of the guard rail spar is pivoted upward so that larger vehicles can slide along the spar until they can stand.

Der an dem Pfosten angeschraubte Schenkel an dem Abstandshalter wird beim Aufprall dann verbogen, wobei er die Schwenkachse für das Hochschwenken des Schutzplankenholms bildet.The bolted to the post leg on the spacer is then bent during impact, where it forms the pivot axis for pivoting the guard rail spar.

Die Verschraubung des Schenkels des Abstandshalters mit dem Pfosten wird erfindungsgemäß genutzt, um mit dieser Schraube den Befestigungbügel mit dem einen Endabschnitt an dem äußeren Flansch des Pfostens zu befestigen. Damit können erfindungsgemäß bereits bestehende Schutzplanken in einfacher Weise nachgerüstet werden.The screwing of the leg of the spacer with the post is used according to the invention with this screw the mounting bracket with the one end to attach to the outer flange of the post. This can be retrofitted according to the invention already existing barriers in a simple manner.

Der zweite, untere Endabschnitt des Befestigungsbügels wird vorzugsweise unter dem Schenkel des Abstandshalters mit dem äußeren Flansch des Pfostens verschraubt. Er ist also an der Außenseite des äußeren Flansches angeordnet.The second, lower end portion of the mounting bracket is preferably bolted to the outer flange of the post under the leg of the spacer. It is therefore arranged on the outside of the outer flange.

Als Pfosten werden vorzugsweise Pfosten mit einem Sigma-Profil verwendet, die außer dem von dem Schutzplankenholm abgewandten, äußeren Flansch einen zweiten, dem Schutzplankenholm zugewandten, inneren oder vorderen Flansch besitzen.As posts preferably posts are used with a sigma profile, which have a second, facing the guard rail, inner or front flange in addition to the remote from the guard rail, the outer flange.

Der zweite, untere Endabschnitt des Befestigungsbügels wird dabei mit einer Schraube verschraubt, die sowohl den äußeren wie den inneren Flansch des Pfostens durchsetzt.The second, lower end portion of the mounting bracket is screwed with a screw, which passes through both the outer and the inner flange of the post.

Diese Schraube kann darüber hinaus zur Versteifung des Pfostens genutzt werden, um zu verhindern, dass der Pfosten bei einem Aufprall abgerissen wird. Dazu können beispielsweise auf die Schraube zwei Muttern aufgeschraubt werden, die sich jeweils an der Innenseite des äußeren Flansches und an der Innenseite des inneren Flansches des Pfostens abstützen. Vorzugsweise durchragt die Schraube jedoch eine Distanzhülse, die sich zwischen der Innenseite des äußeren Flansches und der Innenseite des inneren Flansches des Pfostens erstreckt.This screw can also be used to stiffen the post to prevent the post from being knocked off in a crash. For this example, two nuts can be screwed onto the screw, which are respectively supported on the inside of the outer flange and on the inside of the inner flange of the post. Preferably, however, the screw extends through a spacer sleeve which extends between the inside of the outer flange and the inside of the inner flange of the post.

Der Schenkel an dem Abstandshalter, mit dem der eine Endabschnitt des Befestigungsbügels verschraubt ist, wird vorzugsweise durch eine Klam mer gebildet, wie sie standardmäßig zur Befestigung des Abstandshalters an den Profilpfosten, insbesondere den Sigma-Pfosten einer Schutzplanke verwendet wird. Der zweite Schenkel dieser Klammer wird vorzugsweise mit dem inneren Flansch des Profilpfostens verschraubt. Dabei ist die Verschraubung so ausgelegt, dass sie beim Hochschwenken des Abstandshalters bei einem Aufprall ausreißt.The leg on the spacer, with which the one end portion of the mounting bracket is screwed, is preferably by a Klam mer, as used by default for attachment of the spacer to the profile post, in particular the sigma post of a guardrail. The second leg of this clip is preferably bolted to the inner flange of the profile post. The screw is designed so that it tears when swinging the spacer in an impact.

Die Wirksamkeit des aus den Gewindestäben gebildeten Zuggliedes wird durch das Ausreißen dieser Verschraubung an der Aufprallstelle nicht beeinträchtigt und damit auch nicht das Rückhaltevermögen der Schutzplanke.The effectiveness of the tension member formed from the threaded rods is not affected by the tearing of this screw at the point of impact and thus not the retention capacity of the guardrail.

Der Befestigungsbügel, der vorzugsweise aus Flachstahl besteht, übergreift vorzugsweise mehrere Gewindegänge des Gewindestabs. Das heißt, der Bügel ist als Schelle ausgebildet und weist beispielsweise eine Breite von 20 bis 70 mm auf. Der Befestigungsbügel besitzt damit einen Versagungswiderstand, der deutlich höher ist als beispielsweise der eines Bügels aus einem gebogenen Rundstab.The mounting bracket, which preferably consists of flat steel, preferably overlaps a plurality of threads of the threaded rod. That is, the bracket is formed as a clamp and has, for example, a width of 20 to 70 mm. The mounting bracket thus has a resistance to failure, which is significantly higher than, for example, a bracket made of a curved rod.

Der Befestigungsbügel weist beiderseits des bogenförmigen Abschnitts, der den Gewindestab aufnimmt, jeweils einen Endabschnitt auf, die flächig aufliegen, und zwar der obere Endabschnitt vorzugsweise an dem äußeren Schenkel der Klammer und der untere Endabschnitt vorzugsweise darunter an der Außenseite des äußeren Flansches des Pfostens.The mounting bracket has on both sides of the arcuate portion which receives the threaded rod, each having an end portion which lie flat, namely the upper end portion preferably on the outer leg of the clip and the lower end portion preferably below it on the outside of the outer flange of the post.

Der als Schelle ausgebildete Befestigungsbügel macht die dynamische Bewegung des Gewindestabs mit. Er baut die Kräfte bzw. Energie des Aufpralls sukzessive ab, weil er flexibel und nicht starr ist. Damit hat der aus Flachstahl bestehende Befestigungsbügel einen Art Federwirkung.The trained as a clamp mounting bracket makes the dynamic movement of the threaded rod. It successively reduces the forces or energy of the impact, because it is flexible and not rigid. Thus, the existing flat steel mounting bracket has a kind of spring action.

Der bogenförmige Abschnitt des Bügels ist mit einem dem Durchmesser des Gewindestabs entsprechenden Kreisdurchmesser ausgebildet.The arcuate portion of the bracket is formed with a diameter corresponding to the diameter of the threaded rod diameter.

Weil erfindungsgemäß der Gewindestab frei, flexibel und dynamisch beweglich ist, kann er die Energie und die Kräfte des Aufpralls aufnehmen und weiterleiten. Die Verformung des Gewindestabs wird nicht eingeschränkt oder blockiert, vielmehr ist eine flexible Bewegung je nach den einwirkenden Kräften, also eine dynamische Verformung und Weiterleitung der Aufprallkräfte durch den Gewindestab möglich. Dadurch ist bei der erfindungsgemäßen Schutzplanke die Deformation der Pfosten bei einem Aufprall wesentlich geringer, selbst wenn der Schutzplankenholm stark eingedrückt worden ist. Da die Pfosten weniger deformiert und damit weniger in Aufprallrichtung gebogen werden, hält die erfindungsgemäße Schutzplanke insgesamt einem Aufprall wesentlich besser Stand.Because according to the invention the threaded rod is free, flexible and dynamically movable, it can absorb and forward the energy and the forces of the impact. The deformation of the threaded rod is not limited or blocked, but a flexible movement depending on the forces acting, so a dynamic deformation and transmission of the impact forces by the threaded rod is possible. As a result, in the crash barrier according to the invention, the deformation of the pillars in the event of a collision is considerably lower, even if the guard rail spar has been strongly pressed in. Since the posts are less deformed and thus less bent in the direction of impact, the guard rail according to the invention as a whole withstands an impact much better.

Wie bei Distanzschutzplanken üblich, weist der Abstandshalter an seinem von dem Schutzplankenholm abgewandten, hinteren Ende eine Lasche zur Befestigung eines Abspanngurtes auf. Damit bleibt die Wirkung des Abspanngurtes neben der Wirkung des aus den Gewindestäben gebildeten Zuggliedes in vollem Umfang erhalten.As usual with distance protection planks, the spacer has a tab for fastening a guy belt at its rear end facing away from the guard rail spar. Thus, the effect of the guy belt is retained in full extent next to the effect of the tension member formed from the threaded rods.

Die Schutzplankenholme, die Abstandhalter und die Pfosten werden vorzugsweise aus Stahlprofilen gebildet, insbesondere feuerverzinkten Stahlprofilen, und zwar insbesondere aus einem W-Profil für die Holme und einem Profil mit vorzugsweise einem oberen und einem unteren Flansch für die Abstandshalter, wie bei den heutzutage verbauten Distanzschutzplanken üblich.The guard rails, the spacers and the posts are preferably formed from steel profiles, in particular hot-dip galvanized steel profiles, in particular from a W-profile for the spars and a profile with preferably an upper and a lower flange for the spacers, as in the distance protection planks installed today common.

Dabei kann die Distanzschutzplanke als einfache Distanzschutzplanke mit in den Boden gerammten Pfosten ausgebildet sein, als einfache Distanzschutzplanke auf Brücken und anderen Ingenieurbauwerken, als doppelte Distanzschutzplanke mit in den Boden gerammten Pfosten oder als doppelte Distanzschutzplanke auf Brücken und anderen Ingenieurbauwerken.The distance protection plank can be designed as a simple distance protection plank with rammed into the ground posts, as a simple distance protection plank on bridges and other engineering structures, as a double distance protection plank with rammed into the ground pillars or as a double distance protection plank on bridges and other engineering structures.

Die Pfosten können auf einer Bodenplatte befestigt sein, beispielsweise einem Betonfundament, z. B. verschraubt oder in den Boden eingelassen, um sie am Boden zu befestigen und abzustützten.The posts can be mounted on a base plate, such as a concrete foundation, z. B. bolted or embedded in the ground to secure it to the ground and supported.

Als Gewindestäbe für das Zugglied werden vorzugsweise Gewindestäbe aus Stahl verwendet, wie sie z. B. standardmäßig in der Bewehrungs- und Geotechnik zum Einsatz kommen. Diese Gewindestäbe weisen ein Grobgewinde mit Abflachungen auf gegenüberliegenden Seiten auf.As threaded rods for the tension member threaded rods made of steel are preferably used, as z. B. come standard in the reinforcement and geotechnical equipment used. These threaded rods have a coarse thread with flats on opposite sides.

Der Durchmesser der Gewindestäbe kann beispielsweise 12 bis 40 mm betragen, die Höhe der Gewinderippen beispielsweise 0,6 bis 4 mm und der Abstand der Gewinderippen voneinander beispielsweise 0,5 bis 2,5 cm von Rippenmitte zu Rippenmitte. Dabei kann z. B. ein im Handel erhältlicher Stahlgewindestab verwendet werden, der beispielsweise eine Streckgrenze von 200 bis 800 N/mm2 und eine Zugfestigkeit von 300 bis 1200 N/mm2 aufweist.The diameter of the threaded rods may for example be 12 to 40 mm, the height of the threaded ribs, for example, 0.6 to 4 mm and the distance between the thread ribs, for example, 0.5 to 2.5 cm from rib center to rib center. It can be z. Example, a commercially available steel threaded rod are used, for example, has a yield strength of 200 to 800 N / mm2 and a tensile strength of 300 to 1200 N / mm2.

Das heißt, sie weisen einen von dem Schutzplankenholm 4 abgewandten, äußeren oder hinteren Flansch 15 und einen dem Schutzplankenholm 4 zugewandten inneren Flansch 16 auf.The posts 6 are made of section steel, namely a sigma profile. That is, they have a remote from the guard rail spar 4, outer or rear flange 15 and the guard rail spar 4 facing inner flange 16.

Der Abstandshalter 5 ist mit einer Klammer 17 an dem Pfosten 6 befestigt. Wie insbesondere aus Figur 2 ersichtlich, weist die Klammer 17 dazu einen äußeren Schenkel 18 auf, der an der Außenseite des äußeren Flansches 15 des Pfostens 6 flächig anliegt, sowie einen inneren Schenkel 19, der an der Außenseite des inneren Flansches 16 des Pfostens 6 flächig anliegt. Zwischen den beiden Schenkeln 18 und 19 weist die einteilige Klammer 17 einen plattenförmigen Zwischenabschnitt 20 auf, der an dem plattenförmigen Abschnitt 10 des Abstandshalters 5 flächig anliegt und mit diesem durch Schrauben 21 drehfest verbunden ist. An dem oberen Ende der beiden Schenkel 18, 19 sind nach innen gebogene Laschen 23, 24 vorgesehen, die die obere Kante des Flansches 15 bzw. 16 des Pfostens 6 übergreifen.The spacer 5 is fixed to the post 6 with a bracket 17. As in particular from FIG. 2 can be seen, the bracket 17 has an outer leg 18 which abuts flat against the outer side of the outer flange 15 of the post 6, and an inner leg 19 which on the Outside of the inner flange 16 of the post 6 rests flat. Between the two legs 18 and 19, the one-piece bracket 17 has a plate-shaped intermediate portion 20 which rests flat against the plate-shaped portion 10 of the spacer 5 and is rotatably connected thereto by screws 21. At the upper end of the two legs 18, 19 inwardly bent tabs 23, 24 are provided, which engage over the upper edge of the flange 15 and 16 of the post 6.

Der äußere Schenkel 18 der Klammer 17 ist mit einer Schraube 25 an dem äußeren Flansch 15 des Pfostens 6 befestigt und der innere Schenkel 19 mit einer Schraube 26 an dem inneren Flansch 16.The outer leg 18 of the bracket 17 is fastened with a screw 25 to the outer flange 15 of the post 6 and the inner leg 19 with a screw 26 on the inner flange 16th

Der Abspanngurt 7 ist an einer Lasche 27 des Abstandshalters 5 mit einer Schraube 28 befestigt.The guy belt 7 is attached to a tab 27 of the spacer 5 with a screw 28.

Insoweit entspricht die Schutzplanke 1 im Wesentlichen einer Schutzplanke, wie sie heutzutage an Straßen verbaut ist.In that regard, the guard rail 1 essentially corresponds to a guard rail, as it is installed on roads today.

Gemäß Figur 1 weist die nachgerüstete Schutzplanke 1 ein Zugglied 29 aus mit Schraubmuffen 32 verbundenen Gewindestäben 30 auf, welche mit Befestigungsbügeln 33 an der Außenseite der äußeren Flansche 15 der Pfosten 6 befestigt sind.According to FIG. 1 the retrofitted guardrail 1 a tension member 29 made of threaded sleeves 32 threaded rods 30 which are secured with mounting brackets 33 on the outside of the outer flanges 15 of the post 6.

Der Befestigungsbügel 33 ist als einteilige Schelle ausgebildet. Das heißt, er besteht aus Flachstahl und weist eine Breite b (Figur 4) von beispielsweise 20 bis 70 mm auf, sodass er sich über mindestens zwei Gewindegänge des Gewindestabes 30 erstreckt. Die Dicke d (Figur 3) des Flachstahls kann beispielsweise 2 bis 6 mm betragen.The mounting bracket 33 is formed as a one-piece clamp. That is, it is made of flat steel and has a width b ( FIG. 4 ), for example, 20 to 70 mm, so that it extends over at least two threads of the threaded rod 30. The thickness d ( FIG. 3 ) of the flat steel may be, for example, 2 to 6 mm.

Der Befestigungsbügel 33 besteht aus einem mittleren U-förmigen Abschnitt 34 und zwei Endabschnitten 35, 36.The mounting bracket 33 consists of a central U-shaped portion 34 and two end portions 35, 36th

Der mittlere Abschnitt 34 setzt sich, wie insbesondere aus Figur 3 ersichtlich, aus einem bogenförmigen Abschnitt 37 und zwei im Wesentlichen planparallelen Abschnitten 38, 39 zusammen, die den bogenförmigen Abschnitt 37 mit dem einen bzw. anderen Endabschnitt 35, 36 verbinden. Der bogenförmige Abschnitt 37, der einen Innendurchmesser D aufweist, der dem Außendurchmesser des Gewindestabs 30 entspricht, erstreckt sich über einen Winkel a von mehr als 180°C, also beispielsweise 210° um den Umfang des Gewindestabs 30.The middle section 34 settles, as in particular FIG. 3 can be seen, from an arcuate portion 37 and two substantially plane-parallel portions 38, 39 together, which connect the arcuate portion 37 with the one or the other end portion 35, 36. The arcuate portion 37, which has an inner diameter D corresponding to the outer diameter of the threaded rod 30, extends over an angle a of more than 180 ° C, so for example 210 ° around the circumference of the threaded rod 30th

Die Endabschnitte 35 und 36 des Befestigungsbügels 33 verlaufen im Wesentlichen senkrecht zu den Abschnitten 38, 39 des U-förmigen Abschnitts 34. Dabei liegt der sich von dem U-förmigen Abschnitt 34 nach oben erstreckende Endabschnitt 35 an der Außenseite des äußeren Schenkels 18 der Klammer 17 flächig an, während sich der von dem U-förmigen Abschnitt 34 nach unten erstreckende Endabschnitt 36 an der Außenseite des äußeren Flansches 15 des Pfostens 6 flächig anliegt, wie insbesondere aus Figuren 2 und 3 ersichtlich.The end portions 35 and 36 of the mounting bracket 33 are substantially perpendicular to the portions 38, 39 of the U-shaped portion 34. In this case, the upwardly extending from the U-shaped portion 34 end portion 35 is located on the outside of the outer leg 18 of the clip 17 flat, while the extending from the U-shaped portion 34 downwardly extending end portion 36 on the outside of the outer flange 15 of the post 6 is flat, as in particular from Figures 2 and 3 seen.

Durch die parallelen Abschnitte 35 und 36 des U-förmigen Abschnitts 34 des Befestigungsbügels 33 ist der Gewindestab 30 von dem äußeren Schenkel 18 der Klammer 17 und dem äußeren Flansch 15 des Pfostens 6 in einem Abstand angeordnet, der beispielsweise die Hälfte des Außendurchmessers des Gewindestabs 30 oder mehr betragen kann.By the parallel portions 35 and 36 of the U-shaped portion 34 of the mounting bracket 33, the threaded rod 30 is disposed from the outer leg 18 of the bracket 17 and the outer flange 15 of the post 6 at a distance, for example, half the outer diameter of the threaded rod 30th or more.

Beide Endabschnitte 35, 36 des Befestigungsbügels 33 sind mit dem Pfosten 6 verschraubt. Dazu ist der eine, obere Endabschnitt 35 des Befestigungsbügels 33, der an dem äußeren Schenkel 18 der Klammer 17 anliegt, mit der Schraube 25 mit dem äußeren Flansch 15 des Pfostens 6 verschraubt, welche dazu den äußeren Schenkel 19 der Klammer 17 durchsetzt.Both end portions 35, 36 of the mounting bracket 33 are bolted to the post 6. For this purpose, the one, upper end portion 35 of the mounting bracket 33, which rests against the outer leg 18 of the bracket 17, bolted to the screw 25 with the outer flange 15 of the post 6, which passes through the outer leg 19 of the bracket 17.

Demgegenüber ist der zweite, nach unten ragende Endabschnitt 36 des Befestigungsbügels 33, der an dem äußeren Flansch 15 des Pfostens 6 flächig anliegt, mit einer Schraube 41 mit dem Pfosten 6 verschraubt, die sowohl den äußeren Flansch 15 wie den inneren Flansch 16 des Pfostens 6 durchsetzt.In contrast, the second, downwardly projecting end portion 36 of the mounting bracket 33, which rests flat against the outer flange 15 of the post 6, screwed with a screw 41 to the post 6, both the outer flange 15 as the inner flange 16 of the post. 6 interspersed.

Dabei durchragt die Schraube 41 eine sich zwischen der Innenseite des äuβeren und des inneren Flansches 15, 16 erstreckende Distanzhülse 42 beispielsweise aus Stahl.In this case, the screw 41 extends through a between the inside of the outer and the inner flange 15, 16 extending spacer sleeve 42, for example made of steel.

Gemäß Figur 3 sind die Schrauben 25 und 41 mit Kontermuttern 43, 44 fixiert. Auch sind beiderseits jeder Schraubmuffe 32 auf dem einen bzw. anderen der damit verbundenen Gewindestäbe 30 nicht dargestellte Kontermuttern aufgeschraubt.According to FIG. 3 the screws 25 and 41 are fixed with lock nuts 43, 44. Also, both sides of each screw sleeve 32 are screwed on one or the other of the associated threaded rods 30 not shown lock nuts.

Beim Aufprall eines Fahrzeuges wird der Schutzplankenholm 4 entsprechend dem Pfeil P nach oben geschwenkt, wobei die Schwenkachse, die sich in Längsrichtung der Schutzplanke 1 erstreckt, im Bereich des Schenkels 18 der Klammer 17 liegt. Die Verbindung des inneren Schenkels 19 der Klammer 17 mit dem inneren Flansch 16 des Pfostens 6 durch die Schraube 26 kann dabei reißen. Die Verbindung des äußeren Flansches 15 des Pfostens 6 mit dem äußeren Schenkel 18 der Klammer 17 durch die Schraube 25 bleibt aufgrund der Unterstützung durch den Gewindestab 30 erhalten. Auch ist ein Abreißen des Pfostens 6 aufgrund der Versteifung des Pfostens 6 durch die Distanzhülse 42 verhindert. Damit kann auch ein großes Fahrzeug, wie ein Bus oder Lastwagen, bei einem Aufprall entlang dem Schutzplankenholm 4 gleiten, bis er zum Stehen kommt.Upon impact of a vehicle, the guard rail 4 is pivoted upward in accordance with the arrow P, wherein the pivot axis which extends in the longitudinal direction of the protective barrier 1, in the region of the leg 18 of the bracket 17 is located. The connection of the inner leg 19 of the bracket 17 with the inner flange 16 of the post 6 by the screw 26 can thereby break. The connection of the outer flange 15 of the post 6 with the outer leg 18 of the bracket 17 by the screw 25 is maintained due to the support of the threaded rod 30. Also, a tearing of the post 6 due to the stiffening of the post 6 prevented by the spacer 42. Thus, a large vehicle, such as a bus or truck, in an impact along the guard rail spar 4 slide until it comes to a stop.

Zur Befestigung des Befestigungsbügels 33, der als Spannschelle ausgebildet ist, an dem Pfosten 6 mit der Distanzhülse 42 ist die Schraube 41 als Zylinderschraube mit Innensechskant oder allgemein Innenmehrkant und Federring und Sechskantmutter als Kontermutter ausgebildet, ebenso die Schrauben 25, 26 und 28, um den beengten Platzverhältnissen Rechnung zu tragen.To fasten the mounting bracket 33, which is designed as a clamp, to the post 6 with the spacer sleeve 42, the screw 41 is formed as a socket screw with hexagon socket or generally polygon socket and spring washer and hex nut as locknut, as well as the screws 25, 26 and 28 to the tight space conditions to take into account.
